Gypsum plaster models of unbonded prestressed concrete beams
Results of tests on 18 unbonded prestressed beams of 6 ft 3 in. and 3 ft 3 in. span; part of beam was made of concrete using high tensile steel wire and other part of autoclaved gypsum using phosphor bronze wire; plaster used in models had relatively greater tensile stress and strain capacity than concrete; plaster beams predicted ultimate moment of prototype to within 4%, on high side. (See also - n 660 July 1961 p 906-9)
